Y.sub.1 =H, C1-C5 hydrocarbon, or hydroxyl at any position along R.sub.1 Y.sub.2 =H, C1-C5 hydrocarbon, or hydroxyl at any position along R.sub.1 R.sub.2 =H, or salt. ### Claim 3 (depends on 1) The composition, according to claim 1, wherein said first ingredient has from about fifteen to about twenty carbons. ### Claim 4 (depends on 1) The composition, according to claim 1, wherein said first ingredient is a mixture of monocarboxylic acids or salts thereof. ### Claim 5 (depends on 1) The composition, according to claim 1, wherein said first ingredient is saturated and unsubstituted. ### Claim 6 (depends on 1) The composition, according to claim 1, wherein said first ingredient is oleic acid or a salt thereof. ### Claim 7 (depends on 1) The composition, according to claim 1, wherein said second ingredient is an avermectin. ### Claim 8 (depends on 1) The composition, according to claim 1, wherein said second ingredient is a milbemycin. ### Claim 9 (depends on 1) The composition, according to claim 1, wherein said second ingredient is an ivermectin. ### Claim 10 (depends on 1) The composition, according to claim 1, wherein said composition is formulated to be a drench product to be applied to livestock or pets. ### Claim 11 (depends on 10) The composition, according to claim 10, wherein said first ingredient has from about seven to about eighteen carbons. ### Claim 12 (depends on 11) The composition, according to claim 11, wherein said first ingredient is decanoic or nonanoic acid or salts thereof. ### Claim 13 (depends on 1) The composition, according to claim 1, wherein said first ingredient is a metal salt of a monocarboxylic acid. ### Claim 14 A method for the control of a pest, said method comprising the administration to said pest of an effective amount of a composition comprising a first ingredient which is a monocarboxylic acid having about seven to about twenty carbons, or a salt thereof, or a mixture of monocarboxylic acids or salts thereof, and a second ingredient which is an avermectin, ivermectin, or milbemycin, wherein said first ingredient is applied at a rate of at least about 1 lb/acre, and said second ingredient is applied at a rate of about 0.0006 lbs/acre to about 0.02 lbs/acre. ### Claim 15 (depends on 14) The method, according to claim 14, wherein said first ingredient can be represented by the following formula: R.sub.1 Y.sub.1 Y.sub.2 COOR.sub.2 wherein R.sub.1 =C6 to C19 saturated or unsaturated hydrocarbon, or an epoxide, or cyclopropane thereof Y.sub.1 =H, C1-C5 hydrocarbon, or hydroxyl at any position along R.sub.1 Y.sub.2 =H, C1-C5 hydrocarbon, or hydroxyl at any position along R.sub.1 R.sub.2 =H, or salt. ### Claim 16 (depends on 14) The method, according to claim 14, wherein said first ingredient has from about fifteen to about twenty carbons. ### Claim 17 (depends on 14) The method, according to claim 14, wherein said first ingredient is oleic acid or a salt thereof. ### Claim 18 (depends on 14)
